A
special OEM version of the TI-74 Basicalc. This one was
sold to the German assurance company Hamburg-Mannheimer and usually used
together with the PC-324 battery operated printer.

The
TI-74S followed the TI-58 concept with the
Solid State Software Modules™ and introduced customized ROM-modules that
fitted into the slot on the right side of the display. The
modules are programmable with an additional tool and could be erased with an UV
light source.

Main customers of the TI-74S were assurance and insurance companies. Some
applications used a lot of different modules in boxes holding four of them, each.
